James and I ended up doing a build system for Fotango, lots of people have done a build system, it is a pretty boring task. The boring task is really all the mindlessly stupid things you need to do to build C libraries that Perl modules require, these C modules usually have unusual installation systems or require vastly different options. So CPAN modules install easy, 3rd party stuff is nasty.

So, suddenly an idea struck me, Alien packages! Imagine a CPAN module that has as its only task to make sure a certain library is installed! That means that you can write all the voodoo in your Build.PL file and then just make sure the module requires the correct Alien module! Then anything that install Perl modules will deal with it automatically!

The reason this is so loosely worded is because we have no idea what common functionality will be needed, so we will let evolution work for us and see what individual Alien packages need and then eventually factor it out into this packages. I would like to avoid a topdown design approach.
